COKE-OVEN. BURNER.

Original application led September 8, 1914, Serial'No. 860,583.

Sera'No. 15,286.

To Il Hzom it may concern:

Be it known that I, An'rncn Roman'rs, a citizen of the United States, residing at Evanston, in the county of Cook and btate of Illinois, have invented certain new and useful Improvements in Coke-Oven Burners, of which the following is a specification.

The present invention has reference to certain'improvements in coke oven burners, and as to certain features herein shown is a division of Letters Patent of the United States, No. 1,132,685, which was issued March 23, 1915. in the said patent, have disclosed a coke oven burner embodying certain features of construction and opera tion, and the burner of the present invention embodies sone of the said features. However, the particular form of burner illustrated in this present application is very similar to that shown in my co-pending application for Letters Patent of the United States on improvements in recuperative cone fvens, berial No. 875,503, which was filed December L1, 1914.

VThe main object of the present invention is to provide a construction of burner such that the ccmbustion .of fuel gas may be enected in a practically iiameless manner and by a direct union of the gas with. the oxvgen of the air. ln this connection, another object is to so construct the Aburner that the desired nameless combustion ma)7 be secured when using either preheated or fresh air.

I Another object of the invention is to con-f struct the burner Ifrom standard forms of tile, porcelain, 'silica bloclf. or the like. which forms can be very easily and readilyv mamifactured, and which can aiterward beset together at the coke oven plant when building up the ovens. ln this connection, another object is to so form these standard parts that they may be used for building,r up burners for handling either preheated or cold air. 'In this way, the standard parts of the oui-ner will he made of universal ap-.

plicabilitv, so that they can be used with ovens designed for operation on either cold \Or preheated air.

Ancther o|ect of the invention' is to so form the burner that its various sections can bereadilyl removed for replacement or repair, a-ndwithout the necessity of dismantling largeportions of the oven. 4Bv the acccmplishment of this object', I make. it possible to etect :the necessary repairs ata Specification of Letters atent.

Divided and this application led March minimum cost, and with a minimum amount of disturbance to the oven operation.

Uther objects and uses i'ill appear from a detailed description of the invention which consists in the features of construction and combinatimis of parts hereinafter described and claimed.

In the drawings: Figure 1 shows a cross section through the upper portions of two adjacent ovens equipped with burners embodying the features of the present invention, the construction illustrated being designed particular-l)7 for operation on c'old air: llig'. 2 shows an enlarged detailv section of a portion of the parts shown in Fig. 1;' Fig. 2:3v shows a cross section similar to Fig. 1. -with the exception that the burners in the present case are intended for operation with preheated air supplied from fines or passages extending p between adjacent ovens; Fig. L1- `is an enlarged detail of a portion of the construction shown in Fig. 3; Figs. and@ show in enlarged detail the lower or .nozzle section of the burner: Figs. T and 8 show in enlarged detail one ofthe intermediate sections of the burner; Figs] 9 and 10 show in enlarged detail the upper section 'of the burner; Figs. 11, 1Q, and 13 show in enlarged detail the construction of a modiiicd intermediate section such as ma)v be used when the burner Vis to be employed with preheated air delivered from the side; Fig. 14 is a detail section through the nozzle 'll used in thev arrangement shown in Figs. 1 and 2; and Figs. 15 and 1G are detail views of the sight hole construction used with the burner.

l will first describe the arrangement shown in Figs. 1 and 2. inasmuch as the same is intended particilariv for the handling of cold air, and inasmuch as the burner construction therein illustrated is substantiallv the same in its essential features as that illustrated in Figs. 3 and 4.

ln the arrangement shown in `Figs. 1 and 2, l have illustrated the two adjacent carbonizing chambers 17 and 18. Each of these has the heating walls 19 and (20. and for purpcses ot convenience have'illustrated these heating walls as being of the general type disclosed in my co-iiending application for Letters Patent ot the United States, Serial No. 860,583. The adjacent ovens Aa separated by a partiticn wall 21 which is' also illustrated in the said co-pending'"ap' plication.

tions.

Above each of the partition walls are outer surface tapered to seat nicely intothe taper of the circular hole in the lowermost block 24. One or more sections 26 are consecutively seated above the sections 25 so as to build up the burner to the desired height or length. Ordinarily two lof thesel sections 26 will be used where the airv and gas are bothl supplied from the top in the manner illustrated in Figs. 1 and 2. Finally an upper section 27 completes the upper end of the burner so as to carry the same flush or substantially flush with the top of the heating walls.

As shown in the detail Figs. 5 to 10 inclusive, the upper end of each of the sections 25 and 26 is provided with a anged or flared counter bore 28. The counter bore of the section 25 receives a complementary neck 29 on the section 26, and the counter' bore of the section 26 receives a complementary neck 30 on the section 27. rlhe upper end ofthe section 27 is provided with a shouldered recess 31 slightly larger in diameter than the lower end of the pipe 32, which delivers the air and gas to the burner. The

upper end 33 of this vshouldered recess'is preferably iiared as shown in Figs. 2, 9, and

, 10, and grouting may be run in around the lower end of the ypipe 32 so as to make a tight joint. f

It will be observed from Figs. 2, 9, and 10, that the bore 34 of the section 27 is smaller in diameter than the bore 35 of the sections'25 and 26. The lower end of the neck 30 isA provided with a collar 36 of diameter substantially the same as the bore 35, and said co-llar seating down a slight distance into the bore of the intermediate section 26. burner sections are set together, they may be joined to each other by thin cement or grouting, orthey may be simply allowed to rest one en top of the other.

Where the air is unpreheated, the pipe 32 crnducts a mixture of air and gas from the manifolds 22 and 23 to its burners.y The valves 37 and 38 are for the purpose of controlling the rirnness at' this mixture, as well as the rate of delivery of the mixture to the burner. The valve 37 delivers the'air to a gas and air mixer 38, shown in 'detail in Fig. 14. This mixer has a nozzle discharge opening `39 which draws the ga'sI In practice, when the variousA the air and gas mixture to the b urner. as well as greatly improving the mixing effect.4

'lhe-v collar 36 on the section 27 serves greatly to assist in preventing any back Hash `up through the burner and into the pipe 32, and also assists in securing the tight connectionbetween the section 27 and the intermediate section 26.k By closely incasing'the burner sectionsin the blocksll, heat is readily transmitted from the burners into the walls, so that the burners themselves will not become excessively heated ivy l` i radiation from the white hot walls beneath them. It will be understood that thecombustion does not commence until the gases have left the burner, and that/the only heat In the construction shown inFigs. 3 and 4, the air for combustion is supplied directly into the sides of the burners, the gas lbeing delivered from above. In the particular arrangement shown in said-figures, I have illustrated a recuperating wall 40 between the adjacent heatingwvalls of Consecutive ovens, in accordance with the constructionl disclosed in ltheabove mentioned application, Serial No. 875,503. It will be understood, however, that any otherform of lue or air connection might be vsubstituted for delivering the air to the side of the burner.

Vheie this form of construction -is t o be used, one burner section 26 is replaced by a burner section 41 of special construction,

shown in detail in Figs. 11, 12 and 13. This special form has one of itssides cut away to provide a side opening 42 which is suitablyv positioned to lline up with the cross connection 43 from which tlie'air is delivered to the,

burner. It is preferred thatthe overall 'dimensions of the special section 41 be the' same as those of the section 26, so that the one form may be substituted for the other without thenecessity'of modifying the proportions of ctlherparts of the oven'. It will be observed from Fig 4, that, where one of'A the' sections 41 is used, the shoulder 36 ex tends down opposite to the opening 42 so. as

to direct the air past said opening, thus siphoning the gas into said opening in a manner similar `to the action which is secured when using the mixer 38a. The daan.

per 44 illustrated iny Fig. 4 serves the' purpose of controlling the supply of air to its' particular burner.

In order to 'observe the conditions existing within the heating walls, I mount a` sight window in alinement with each burner.

As a simple means of construction, thesey sight windows take the form-of union connections having the members 45 and 4G, between which is clamped a plate of glass or the like 4T.
